In a futures market, if the price is $500/BTC, an investor needs to buy 50 futures contracts, each worth $10. If an investor wishes to open a positive position then he goes long with “buy" contracts, and if he decides to open a negative position, he goes short with “sell” contracts. An investor’s position can be either positive or negative for the same instrument. (For more, see: Bitcoin Mass Hysteria: The Disaster that Brought Down Mt. Gox.)
Two members of the Silk Road Task Force—a multi-agency federal task force that carried out the U.S. investigation of Silk Road—seized bitcoins for their own use in the course of the investigation.[86] DEA agent Carl Mark Force IV, who attempted to extort Silk Road founder Ross Ulbricht ("Dread Pirate Roberts"), pleaded guilty to money laundering, obstruction of justice, and extortion under color of official right, and was sentenced to 6.5 years in federal prison.[86] U.S. Secret Service agent Shaun Bridges pleaded guilty to crimes relating to his diversion of $800,000 worth of bitcoins to his personal account during the investigation, and also separately pleaded guilty to money laundering in connection with another cryptocurrency theft; he was sentenced to nearly eight years in federal prison.[87]
Shares may be issued in advance of receipt by the Trust of all or a portion of the applicable Deposit Securities as described below. In these circumstances, the initial deposit may have a greater value than the NAV of the Shares on the date the order is placed in proper form because, in addition to the available Deposit Securities, cash must be deposited in an amount equal to the sum of (i) the Balancing Amount, plus (ii) up to 115% of the market value of the undelivered Deposit Securities (the “Additional Cash Deposit”). Additional amounts of cash may be required to be deposited with the Trust, pending delivery of the missing Deposit Securities to the extent necessary to maintain the Additional Cash Deposit with the Trust in an amount up to 115% of the daily mark-to-market value of the missing Deposit Securities. Authorized Participants will be liable to the Trust for the costs incurred by the Trust in connection with any such purchases. These costs will be deemed to include the amount by which the actual purchase price of the Deposit Securities exceeds the market value of such Deposit Securities on the day the purchase order was deemed received by the Distributor plus the brokerage and related transaction costs associated with such purchases. The Trust will return any unused portion of the Additional Cash Deposit once all of the missing Deposit Securities have been properly received by the Custodian or any sub-custodian or purchased by the Trust and deposited into the Trust. In addition, a Transaction Fee, as described below, will be charged in all cases. The delivery of Shares so purchased will occur no later than the third Business Day following the day on which the purchase order is deemed received by the Distributor.

When a Fund purchases a put or call option on a futures contract, the Fund pays a premium for the right to sell or purchase the underlying futures contract for a specified price upon exercise at any time during the option period. By writing (selling) a put or call option on a futures contract, a Fund receives a premium in return for granting to the purchaser of the option the right to sell to or buy from the Fund the underlying futures contract for a specified price upon exercise at any time during the option period.
Market conditions should be considered favorable to a Fund when such conditions make it more likely that the value of an investment in that Fund will increase. Market conditions should be considered adverse to a Fund when such conditions make it more likely that the value of an investment in that Fund will decrease. For example, market conditions that cause the level of the S&P 500® to rise are considered “favorable” to the Ultra S&P500® and are considered “adverse” to the Short S&P500®.

During the market slump last week, there was some banter on Reddit that the crash was going to end Wednesday, January 17 at 4:00 PM EST when the markets closed the first Bitcoin futures contracts on the CBOE expired at $10,900 per Bitcoin. There was even a countdown posted by one Reddit user. While the price of Bitcoin did not rocket back up in the immediate aftermath, altcoins started to rebound hours after the futures contracts expired.

Below is a description of various types of money market instruments and other debt instruments that a Fund may utilize for investment purposes, as “cover” for other investment techniques such Fund employs, or for liquidity purposes. Other types of money market instruments and debt instruments may become available that are similar to those described below and in which the Funds also may invest consistent with their investment goals and policies. Each Fund may also invest in pooled investment vehicles that invest in, and themselves qualify as, money market instruments.
Securities (including short-term securities) and other assets are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. Futures contracts and options on securities, indexes and futures contracts are generally valued at their last sale price prior to the time at which the NAV per share of a class of shares of a Fund is determined. Alternatively, fair valuation procedures as described below may be applied if deemed more appropriate. Routine valuation of certain other derivatives is performed using procedures approved by the Board of Trustees.
If you are doing any active trading, set stop losses. For any coins not in your medium or long-term holds, always set stop losses. This is important for several reasons — the most obvious is mitigating your losses. But more importantly, you force yourself to decide on a point of acceptable loss, and because you now have a reference point, you are able to measure your effectiveness to keep or adjust for future trades. Sometimes, during a market dip, altcoins can plummet, and stop losses can lead to profitability by automatically selling for fiat that you can use to re-enter at lower prices.
The Advisor, its principals, officers and employees (and members of their families) and affiliates may participate directly or indirectly as investors in the Advisor’s clients, such as the Funds. Thus the Advisor may recommend to clients the purchase or sale of securities in which it, or its officers, employees or related persons have a financial interest. The Advisor may give advice and take actions in the performance of its duties to its clients that differ from the advice given or the timing and nature of actions taken, with respect to other clients’ accounts and/or employees’ accounts that may invest in some of the same securities recommended to clients.
A Parent Fund’s recognition of any subpart F income from an investment in its Subsidiary will increase the Fund’s tax basis in such subsidiary. Distributions by a Subsidiary to a Parent Fund, including in redemption of its Subsidiary’s shares, will be tax free, to the extent of its Subsidiary’s previously undistributed subpart F income, and will correspondingly reduce the Fund’s tax basis in its Subsidiary, and any distributions in excess of the Fund’s tax basis in its Subsidiary will be treated as realized gain. Any losses with respect to the Fund’s shares of its Subsidiary will not be currently recognized. Subpart F income is generally treated as ordinary income, regardless of the character of a Subsidiary’s underlying income.
I used to find it odd that these hypothetical AIs were supposed to be smart enough to solve problems that no human could, yet they were incapable of doing something most every adult has done: taking a step back and asking whether their current course of action is really a good idea. Then I realized that we are already surrounded by machines that demonstrate a complete lack of insight, we just call them corporations. Corporations don’t operate autonomously, of course, and the humans in charge of them are presumably capable of insight, but capitalism doesn’t reward them for using it. On the contrary, capitalism actively erodes this capacity in people by demanding that they replace their own judgment of what “good” means with “whatever the market decides.”

In May 2018 Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[90] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[91] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[92]

  •   Ownership of bitcoin is pseudonymous and the supply of accessible bitcoins is unknown. There is no registry showing which individuals or entities own bitcoin or the quantity of bitcoin that is owned by any particular person or entity. It is possible, that a small group of early bitcoin adopters hold a significant proportion of the bitcoin that has been thus far created. There are no regulations in place that would prevent a large holder of bitcoin from selling its bitcoins, which could depress the price of bitcoin and have an adverse effect on an investment in the Fund.
The Fund may invest in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.

Distributions of Shares shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants. The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial owners owning through such DTC Participants.
Well since then bitcoin is up more than 50 percent; it reached a record of $19,511 early Monday, hours after CME launched its futures contract. "Bitcoin Climbs as Futures Debut Fails to Incite Attack by Shorts," is the Bloomberg headline about Sunday's start of trading on CME. On the other hand, bitcoin was actually down a bit on the first full day of CME trading yesterday, and fell further overnight; "Bitcoin Futures Prices Fall in CME Debut" is the Wall Street Journal headline about Monday's trading. It is of course still very early days for the futures, and it's still possible that the shorts will come in and drive the price down. I guess it's even possible bitcoin bulls and bears will both flock to the futures market and trade with each other to find an efficient and stable price that reflects bitcoin's fundamental value, whatever that is.

Whether a Fund realizes a gain or loss from futures activities depends generally upon movements in the underlying currency, commodity, security or index. The extent of a Fund’s loss from an unhedged short position in futures contracts or from writing options on futures contracts is potentially unlimited, and investors may lose the amount that they invest plus any profits recognized on their investment. The Funds may engage in related closing transactions with respect to options on futures contracts. The Funds will engage in transactions in futures contracts and related options that are traded on a U.S. exchange or board of trade or that have been approved for sale in the U.S. by the Commodity Futures Trading Commission (“CFTC”).

BitMEX also has a weekly rebalancing for all their contracts, but currently their most popular product is the Daily 100x maximum leverage contract. This settles daily, but otherwise the rest of the contracts are handled on Friday, a little bit after OKCoin's 8:00AM UTC. See this website to get a countdown to the settlements on the different exchanges. The policies of exchanges are changing often so this information may be outdated by the time you read it (though we will try to keep it as up to date as possible).

In contrast, if you are “going short” on Bitcoin, you assume that Bitcoin prices will fall. Buying put options will enable you to sell Bitcoin at some point in the future at a price that is higher than the future price you expect. In analogy to the example above, if the current Bitcoin price is 5,000 USD and you expect it to fall to 2,000 USD in 6 months, then put options allowing you to sell Bitcoin for 5,000 USD in 5 months (when everyone else is selling for 2000 USD) are very valuable.
